Sillimanite Fire Brick


sillimanite fire brick

Sillimanite brick is a kind of quality refractory bricks with various excellent features of high temperature wear resistance and high strength for application in high temperature furnaces. sillimanite refractory brick belongs to neutral refractory. sillimanite refractory block is made of sillimante minerals, which can transform into mullite and free silica after high temperature firing. sillimanite fire block is produced by the methods of high temperature firing and casting. sillimanite bricks are produced with sillimanite minerals through high temperature firing method or slurry casting.

Sillimanite Fire Brick Description

 

Sillimanite bricks are a kind of high quality refractory brick with high refractoriness of 1770~1830℃ and high refractoriness under load of 1500~1650℃, whose physical and chemical property is better than high alumina bricks. Sillimanite transforms into mullite and free silicon dioxide after high temperature firing. Sillimanite refractory bricks generally adopt manufacturing process of high temperature firing and mud mix pouring process.

Composition of Sillimanite Fire Brick

 

Sillimanite fire brick belongs to neutral refractory. Sillimanite brick is made of sillimante minerals, which can transform into mullite and free silica after high temperature firing. sillimanite refractory brick is produced by the methods of high temperature firing and casting.

 

Sillimanite Fire Brick Manufacturing Process

 

Sillimanite bricks are manufactured with main raw material of sillimanite, sillimanite is a kind of quality refractory raw materials and used to produce high alumina brick with low creep, high refractoriness under load, high heat shock and micro-expansive, and furnace top. sillimanite can be transformed into mullite and free silicon dioxide through high temperature firing. sillimanite refractory bricks physical and chemical property are better than high alumina bricks. Sillimanite fire brick refractoriness is 1770~1830 ℃ and apparent initial softening temperature is 1500~1650℃.
